The latter is fixed to the felly F so that the shaft 19 is relatively stationary to the latter with the result that when a suitable tool is placed on the squared end 19' of said shaft and rotated, said cam ring 12 will be moved in a suitable direction.

The shaft 19 also carries a locking plate 21 in which is formed a circle of pin engag ing openings 22, and the shaft bracket supports a sliding locking pin 23. one end of which is designed to be engaged in any one of said holes 22. An expansile spring 24 normally urges the pin toward the locking plate and into engagement with one of the holes therein, but said locking pin 23- is readily shifted at the will of the operator by means of a handle 25, the same being Tpivotally carried by a block26. Thus when the handle 25 is moved toward the gear 18, the sliding pin 23 will be moved in a like 7 direction and thus it will be disengaged from the locking plate 21. Provision is also made for holding the locking pin in inoperative position during the rotation of the shaft 19. .The felly F is provided with one or more rim removing devices, each of which con-' sists of a lever 27, a .rim projecting arm 28 anda stop pin 29. The levers 27 are piv} oted to the folly F in such positions that the arms 28 extend above the shoulder S of the felly band B and, when they are properly rocked the inner side of the rim-R is en .gaged and the same is forced from the felly. Rocking of the levers is procured by trips 30 carried by the cam ring 12. In

to' say in a direction which will cause the release of the rim retaining-arms 1.

The operatlonof the invention issubstane .ti ally and briefly aS follows Assuming that a rim R and a tire carried thereby is to be placed on the fellyof a wheel, the shaft 19 is rotated by a suitable means so that the ends of the rimretaining arms 1 are spaced inwardly of the surface ofthe band B. This movement of the arms 1 is procured by the rocking of the bellcranks 2 through the engagement of the cam direction to shift the bellcranks into the po- 7 sition indicated in Figure 3. In other words the rim engaging portions of the arms 1 will be in contact with the'rimR and the same forced against the shoulder 8'. Any type of rim can thus be effectively held upon its felly. After the rim R is thus engaged bythe rim retaining arms, the locking pin 23 is permitted to engage in one of the holes 22 in the locking plate 21. Accidental rotation of the shaft is thus absolutely prevented and the rim cannot be removed until said cam ring is again shifted. 7 i

If, it should be necessary to remove the rim, the shaft 19 is unlocked and rotated in a manner to cause the release of the rim retaining arms as hereinbefore mentioned. Such a rotation of the shaft with its consequent movement of the cam rin 12 engages the trips 30 with the levers 2 and rocks the same so that said rim is mechanically forced-from the felly. This feature is of considerable importance in readily removing rims which tend to stick or bind,'orthose.
